Note:
Cooling capacities are based on outdoor air temperature of 35°C Dry Bulb with controlled indoor water inlet
temperature of 12°C and water outlet temperature of 7°C.
Heating capacities are based on outdoor air temperature of 7°C Dry Bulb (44.6°F Dry Bulb), 6°C Wet Bulb
(42.8°F Wet Bulb) with controlled indoor water inlet temperature of 30°C and water outlet temperature of 35°C.
Specifications are subjected to change without prior notice for further improvement.
* Above 55°C, only possible with backup heater operation.
** Between outdoor ambient -10°C and -15°C, the water outlet temperature gradually decreases from 60°C to
55°C.
It is recommended to follow DHW tank water quality limit for Panasonic Air to Water All in One according to
Drinking Water Directive 98/83 EC
In case it is necessary to indicate the air flow volume in (l/s), the value in (m
3
/min.) shall be multiplied by 16.7 and
rounded down the decimal point.
If the EUROVENT Certified models can be operated under the “extra-low” temperature condition, -7°C DB and
-8°C WB temperature with rated voltage 230V shall be used.
Flowrate indicated are based on nominal capacity adjustment of leaving water temperature (LWT) 35°C and
ΔT=5°C.
The sound pressure level is measured with distance 1.0m from the unit and height at 1.5m. (Test carry out for
cooling at ambient 35°C DB and Water Out 7°C, heating at ambient 7°C DB / 6°C WB and water out 55°C)
The sound power level is measured with accordance to EN12102 under full load conditions. (Test carry out for
cooling at ambient 35°C DB and Water Out 7°C, heating at ambient 7°C DB / 6°C WB and water out 55°C)
The sound power level is measured with accordance to EN12102 under conditions of the EN14825.
EER and COP classification is at 230V only in occordance with EU directive 2003/32/EC.
